SMOOTHING-IRON WITH DETACHABLE HANDLE.

Specification of Letters Patent.

Patented Dec. 19, 1905.

Application filed December 27, 1904- Serial No. 238,466.

To all whom it natty concern.-

Be it known that I, EMIL HUGO HENNIGER, a subject of the German Emperor,and a resident of Frankfort-on-the-Main, Germany, have invented certainnew and useful Improvements in Smoothing-Irons with Detachable Handles,of which the following is a specification.

The present invention relates to improvements in smoothing-irons havingdetachable handles of that class in which the handle may be attached tothe iron proper by means of a preferably horizontal lug, arm, pin, orthe like to be inserted into a suitable socket, bore, guide or the likewith which the body of the iron is provided, and more particularlyrefers to the device for coupling or connecting the handle to theiron-body.

The object of the improvements is to provide means whereby the handlemay be readily and reliably attached to the iron, so as to make theconnection practically a rigid one in order to prevent the handle or itslug from waggling and jiggling in its socket and to avoid therebyclacking or clappering noises when the smoothing-iron is used forironing. On the other hand, the said improved means is adapted to allowof an easy and ready uncoupling and removal of the handle.

The object aimed at is essentially obtained by means of a cam oreccentric rotatably attached to the handle and adapted to act by itsclamping effect against a suitably-faced projection or the like withwhich the iron-body or its socket for the handle-lug is provided.

In order that my invention may be more fully understood by one skilledin the art to which it appertains, I shall now proceed to describe thesame in detail, reference being taken to the accompanying sheet ofdrawings, in which Figure 1 is a longitudinal vertical section, and Fig.2 a transverse vertical section on the line I II, Fig. 1, of asmoothing-iron constructed in accordance with and embodying myinvention. Fig. 3 is a lateral elevation, and Fig. & a plan of asmoothing-iron, showing a modification of the cam-coupling device. Inthe latter representation the upper part of the handle is shown asbroken away, the camcoupling device as uncoupled, and the lower arm ofthe handle as partly removed from the Socket.

Similar letters of reference refer to like parts throughout the severalfigures.

Referring to Figs. 1 and 2, the body a of the smoothing or sad iron isprovided with a socket Z) or the like. The handle is U-shaped andconsists of two horizontal arms 0 and (Z, connected by a vertical partor stem 6. The arm 0 is furnished with a cover or lining c, of wood orother insulating material, and serves as the handle proper, whereas theother arm (Z is formed to fit into the hollow of the socket b, as thisis well known and evident from the drawings.

For rigidly connecting the U-shaped handle with the body of the sad-ironand to rigidly and reliably lock the armcZ to the socket b I provide acam it, the shaftfof which is rotatably mounted in a suitable bearing eof the stem 0 and provided at'its rear end with a thumb-piece g or thelike. The top face of the socket I) has a recess When it is desired toattach the handle to the smoothing-iron, the arm (Z of the handle isinserted into the socket b. For allowing of such operation the cam itmust previously have been turned so that its eccentric part is directedupward. After the insertion of the arm (Z into the socket b, fitting assnugly as possible into each other, the cam It is opposite the recessa'. When now the cam It is turned in the direction of the arrow shown inFig. 2, the eccentric part of the said cam enters or moves into therecess 5 and clamps the handle-arm (Z firmly to the socket Z), a rigidconnection being thus established between the detachable handle and thebody of the smoothing-iron.

The uncoupling and removal of the handle may be effected in a likesimple manner first by turning the cam in the other direction to bringits eccentric part out of contact with the socket and into the upperposition and then by drawing out the handle-arm (Z from the socket b.

It is supposed that the width of the recess@' corresponds to thethickness of the cam h, so that the latter fits most snugly into therecess; but sometimes after a longer period of use it may occur that theedges of the cam and recess may become worn. In such cases, al-

though the arm clremains firmly clamped to the socket in a verticaldirection, it may yet be liable to jiggle somewhat in its longitudinaldirection, which is caused by the slight difference between thethicknesses of the cam and the width of the recess, as above stated. Inorder to entirely obviate this small drawback and to secure at allevents a rigid coupling or connection between the handle andsmoothing-iron, it is advisable to have the device arranged so that thecam instead of entering a recess catches a suitable shoulder orprojection of the socket and that either the contact-face of theshoulder or the end face of the cam, or both these bearing-faces. arecam-shaped orformed in a helical line, the latter modification beingillustrated by Figs. 3 and 4:. In this arrangement the socket Z) isprovided with a shoulder 6, having a camface 6 whereas the end face ofthe cam it, adapted to bear against the cam-face bi is also cam-shapedor formed in a helical line, as shown at it. WVhen the arm d has beeninserted into the socket b and the cam it is turned down into theposition Fig. 3, the cam-face 7t bears against and slides along thecamface 6 thereby clamping the handle firmly to the socket. By thisarrangement it is possible to eliminate constantly any longitudinal playof the parts to be connected and to thereby avoid any jiggling orclattering of the handle in longitudinal direction.

The handle is detached and removed from the iron in the same manner asdescribed with reference to the handle shown in Figs. 1 and 2viz., byturning up the cam 7t h from the position shown in Fig. 3 into theposition shown'in Fig. 4 and by drawing out the arm d from the socket 6.

Having fully described my invention, what I claim, and desire to secureby Letters Patent, is

1. Asmoothing-iron provided on its upper face with a centrallongitudinal hollow rib or projection, and a handle comprising a handlebar having parallel arms one of which is adapted to be inserted into theaforesaid rib and the othercarrying the handle proper, in combinationwith a cam revolubly mounted on the handle-bar and adapted to engage theupper face of the aforesaid rib.

2. In combination with a sad-iron having a longitudinally-disposedsocket formed there: in, a handle comprising a stem portion, an arm onthe latter adapted to fit said socket, an abutment near the mouth of thesocket having a cam-face, a rotatable shaft mounted in the arm, a cam onsaid shaft having a camface adapted to engage the aforesaid face on theabutment and an arm mounted on the stem parallel to the aforesaid arm.

3. A smoothing-iron provided on its upper face with a centrallongitudinal rib or projection having a bore of polygonal form incrosssection, and a handle comprising a handle-bar provided withparallel arms one of which carries the handle proper and the other ofpolygonal form in cross-section to lit the bore in the aforesaid rib; incombination with a cam revolubly mounted in the handle-bar and adaptedto impinge on the upper face of the WVitnesses:
